UVZ2D3R3MEH

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as "polarized capacitors," are widely used as energy-storage devices in electric circuits. They are common building blocks for a variety of electronic applications ranging from consumer electronics to power electronic applications.

The most significant feature of aluminum electrolytic capacitors is their ability to store large amounts of electrical energy in a very small physical space. This makes them ideal for many applications where there is limited room available. They also have superior capacitance-voltage characteristics and low ESR (Equivalent Series Resistance), making them ideal for both AC and DC applications.

UVZ2D3R3MEH Application Field and Working Principle

UVZ2D3R3MEH is a type of aluminum electrolytic capacitor. This type of aluminum electrolytic capacitor is specifically designed for high-frequency and high-temperature applications, with an operating temperature range up to 125°C. It is used mainly in switch-mode power supplies, AC motors, circuit boards, DC-DC converters, and frequency-tuned amplifiers.

The working principle of the UVZ2D3R3MEH aluminum electrolytic capacitor is based on a chemical reaction between aluminum and an electrolyte solution. When the electrolyte solution is connected to the aluminum, the electrolyte begins to react with the aluminum, forming a layer of aluminum oxide that acts as a dielectric. This creates an electrostatic field in which the amount of energy stored is proportional to the applied voltage at the aluminum electrode.

The internal structure of the capacitor consists of two parts – the anode and the cathode. The anode is the negative terminal and the cathode is the positive terminal. Connecting the two terminals together will form an electric circuit that is able to store energy. The amount of energy stored increases with the applied voltage.

The UVZ2D3R3MEH aluminum electrolytic capacitors are engineered to provide excellent performance in high-frequency applications. It is built with an advanced cathode structure utilizing a special material to ensure a low equivalent series resistance (ESR) and a high Q value (quality factor). This ensures consistent performance over a wide temperature range.

In addition, this type of capacitor is designed to have long life expectancy due to the use of special sealing technology and an enhanced anode-to-cathode installation process. This improves leakage current resistance and the prevention of dry-out, which helps extend the service life of the capacitor.

In summary, the UVZ2D3R3MEH aluminum electrolytic capacitors are ideal for applications where a reliable capacitance is needed, but space constraints are a factor. With their high capacitance-voltage characteristics, superior ESR, and long life expectancy, they are an excellent choice.
